Hi, I have problem in the setup could you give me a hand?
In Clover when I click to start by the pen driver I have the "MACH Reboot" error, as on print.
I have already put the file "OsxAptioFixDrv- 64.efi" in the folder "B/EFI/Clover/drivers64UEFI".

*I downloaded the UEFI version and I could not get it at boot, I select the driver pen and everything goes black and I can not make it to Clover.

I'm exactly where (in terminal) you write amd... then at the end it says: you will need to use the usb to boot for the first time BUT: after rebooting on the HighSierraAMD_V2 usb, I don't see any "Boot to "myhd"... only boot to HighSierraAMD installer. How could I boot my hd ? btw it's a APFS volume. Thank you

@Cap, I am having the exact same issue as you. Were you able to resolve it? as I seem to be having issues doing so myself.

When I try to install the MAC operating system, it shows me the following error does printf work ?, how can I solve it? also try to copy the file in the USB / EFI / Clover / drivers64UEFI directory: but I have not found it.

Using the AMD High Serria_V2 official image by Shanee, I managed to make a bootable USB, and have about 40 GB's of unallocated space on my HDD, separate from my boot drive which is an SSD, to install a copy of High Sierra.
When I select the non UEFI version of my USB to boot from, I am able to reach clover, but when I tell it too boot from mac, it goes through a long process of around 15 minutes, and ends with just a white screen which after transitions to a dark grey screen, and nothing ever happens.

I am completely unable to actually get to the disk manager portion on the very first boot, and the Radeon card fixes didn't change it.
